∙Objects in the RearView Monitor will ap-
pear visually opposite compared to when
viewed in the rearview and outside mirrors.
∙ Use the displayed lines as a reference. The lines are highly affected by the num-
ber of occupants, fuel level, vehicle posi-
tion, road conditions and road grade.
∙ Make sure that the liftgate is securely closed when backing up.
∙ Do not put anything on the rearview camera. The rearview camera is installed
above the license plate.
∙ When washing the vehicle with high pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing water
condensation on the lens, a malfunction,
fire or an electric shock.
∙ Do not strike the camera. It is a precision instrument. Otherwise, it may malfunc-
tion or cause damage resulting in a fire or
an electric shock.
The following are operating limitations and
do not represent a system malfunction: ∙ When the temperature is extremely high or low, the screen may not clearly display
objects. ∙ When strong light directly shines on the
camera, objects may not be displayed
clearly.
∙ Vertical lines may be seen in objects on the screen. This is due to strong reflected
light from the bumper.
∙ The screen may flicker under fluorescent light.
∙ The colors of objects on the RearView Monitor may differ somewhat from the
actual color of objects.
∙ Objects on the monitor may not be clear in a dark environment.
∙ There may be a delay when switching between views.
∙ If dirt, rain or snow accumulate on the camera, the RearView Monitor may not
display objects clearly. Clean the camera.
∙ Do not use wax on the camera lens. Wipe off any wax with a clean cloth dampened
with a diluted mild cleaning agent, then
wipe with a dry cloth.
SYSTEM MAINTENANCE
CAUTION
∙ Do not use alcohol, benzine or thinner toclean the camera. This will cause
discoloration.
∙ Do not damage the camera as the moni- tor screen may be adversely affected.
If dirt, rain or snow accumulates on the cam-
era
1, the RearView Monitor may not dis-
play objects clearly. Clean the camera by wip-
ing it with a cloth dampened with a diluted
mild cleaning agent and then wiping it with a
dry cloth.

When the “[X]” icon is displayed on the
screen, the camera image may be receiving
temporary electronic disturbances from sur-
rounding devices. This will not hinder normal
driving operation but the system should be
inspected. It is recommended that you visit an
INFINITI retailer for this service.SYSTEM MAINTENANCE
CAUTION
∙ Do not use alcohol, benzine or thinner toclean the camera. This will cause
discoloration.
∙ Do not damage the cameras as the moni- tor screen may be adversely affected.
If dirt, rain or snow accumulates on any of the
cameras
1, the Around View® Monitor may
not display objects clearly. Clean the camera
by wiping with a cloth dampened with a di-
luted mild cleaning agent and then wiping
with a dry cloth.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar function as
outlined in this section could result in seri-
ous injury or death.
∙ The sonar is a convenience feature. It is not a substitute for proper parking.
∙ This function is designed as an aid to the driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
∙ The driver is always responsible for safety during parking and other
maneuvers.
∙ Always look around and check that it is safe to move before parking.
∙ Read and understand the limitations of the sonar as contained in this section.
The sonar function helps to inform the driver
of large stationary objects around the vehicle
when parking by issuing an audible and visual
alert.

CAMERA AIDING SONAR (parking
sensor) (if so equipped)
4-24Monitor, climate, audio, phone and voice recognition systems

∙ The system will not detect small objectsbelow the bumper, and may not detect
objects close to the bumper or on the
ground.
∙ The system may not detect the following objects:
– Fluffy objects such as snow, cloth, cotton, grass or wool.
– Thin objects such as rope, wire or chain.
– Wedge-shaped objects.
∙ If your vehicle sustains damage to the bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
jects or false alarms.
CAUTION
Excessive noise (such as audio system vol-
ume or an open vehicle window) will inter-
fere with the tone and it may not be heard.
System temporarily unavailable
When the amber markers are displayed at the
corners of the vehicle icon and the function
cannot be activated from the Camera setting
menu (the setting items are grayed out), the
sonar system may be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors (lo-
cated on the front and rear bumper fascia)
free from accumulations of snow, ice and
dirt. Do not scratch the surface of the sonar
sensors when cleaning. If the sensors are
covered, the accuracy of the sonar function
will be diminished.
4-28Monitor, climate, audio, phone and voice recognition systems

∙ When the Rear View camera has de-tected a blockage (icon will blink).
If the icon light continues to illuminate or-
ange, have the MOD system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
SYSTEM MAINTENANCE
CAUTION
∙ Do not use alcohol, benzine or thinner to clean the camera. This will cause
discoloration.
∙ Do not damage the camera as the moni- tor screen may be adversely affected. If dirt, rain or snow accumulates on any of the
cameras
1, the MOD system may not oper-
ate properly. Clean the camera by wiping
with a cloth dampened with a diluted mild
cleaning agent and then wiping with a dry
cloth.
